1. A power meter system that monitors electrical power characteristics of an electrical circuit connected to a power system, including:
- a power bus having a power bus voltage coupled to a power source having a power source voltage;
a power converter coupled to said power source, said power converter converting said power source voltage to said power bus voltage and electrically isolating said power source from said power bus of said power meter system; and
a plurality of power taps coupled to said power bus,each of said power taps having a ride-through capacitor operatively coupled thereto to provide power to a circuit coupled with said power tap during brief interruptions in said power source to each of said respective power taps, each of said power taps further having a voltage regulator for converting the bus voltage of said power bus to the circuit voltage required for said circuit coupled with said power tap.
